These drawings and written description are not intended to limit the scope of the inventive concepts in any manner, but rather to illustrate the inventive concepts to those skilled in the art by reference to specific embodiments.

Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

The hinge 100 of the present application may be applied in the automotive field, as well as in other technical fields. And are not limited in this application. The automobile can be an internal combustion engine automobile and an electric automobile. Illustratively, the vehicle of the present application may be an electric automobile.

The vehicle is provided with a door 300. The door 300 is a main component of the vehicle. The vehicle door 300 may insulate the exterior of the vehicle door 300 from interference. Such as noise. The appearance of the door 300 may affect the aesthetic appearance of the vehicle as a whole. In the closed state of the door 300, the outer surface of the door 300 may form a smooth surface with the outer surface of the body 200. The structural strength of the vehicle door 300 may affect the safety performance of the vehicle. When the side of the vehicle is impacted by an external force, the door 300 can absorb the side impact to some extent, so that the possibility of injury to passengers in the vehicle can be reduced.

The usability of the vehicle door 300 may affect the convenience of use for the passenger. A passenger may enter or exit the interior space of the vehicle by opening or closing the vehicle door 300. The flexibility of the opening or closing of the door 300 may affect the comfort of passengers getting on or off the vehicle. When the opening angle of the door 300 is small, the convenience of getting on or off the vehicle is easily affected for passengers with large height and weight values.

The door 300 may include a swing type door, a push-pull type door, a gull wing type door, and the like, according to the opening and closing manner classification of the door 300. The door 300 may be mounted to the body 200 by a hinge 100 so that the door 300 may rotate with respect to the body 200 to open or close the door 300. The hinge 100 of the present application may be applied to any of the above-described types of vehicle doors 300. And are not limited in this application. For example, the vehicle door 300 of the present application may be a swing type vehicle door.

In the related art, the opening angle of the rotary vehicle door is small, and especially the front side vehicle door 300 is difficult to satisfy the comfortableness of getting on or off the vehicle at different ages, heights and weights.

In view of the above problems, the applicant has developed a hinge 100, and the following further describes embodiments of the present application.

Referring to fig. 1 and 2, a hinge 100 of the present embodiment includes a body mount 110, a door mount 120, and a transmission assembly 130. The body mount 110 includes a body attachment portion 111 and a first transfer portion 112 connected thereto. The body attachment portion 111 may be used to attach to the body 200. The door carrier 120 includes a door attachment portion 121 and a second adapter portion 122 connected thereto. The door attachment portion 121 may be used to attach to the door 300. The second adaptor 122 is disposed on one side of the door connecting portion 121.

The driving assembly 130 includes a first link 131, a second link 132, a third link 133, and a fourth link 134. The first link 131 and the second link 132 are rotatably connected to the first transfer portion 112. The first link 131 is located on the side of the second link 132 close to the vehicle-body connecting portion 111. The third rod 133 and the fourth rod 134 are rotatably connected to the second adaptor 122. The third link 133 is located on the side of the fourth link 134 near the vehicle body connecting portion 111. The first link 131 and the second link 132 are rotatably connected to the third link 133. The second lever 132 is rotatably coupled to the fourth lever 134.

Wherein the door stay 120 moves closer to or away from the body stay 110 to switch between the closed position or the open position, and the first link 131, the second link 132, the third link 133 and the fourth link 134 switch between the folded state or the unfolded state.

The hinge 100 of the embodiment of the present application may be in a closed state of the door 300 in a folded state. With the hinge 100 in the deployed state, the door 300 may be in an open state. It should be noted that, when the door 300 is in the closed state, at least a part of the door 300 may be located in the inner space of the vehicle body 200. During the unfolding of the hinge 100, the portion of the vehicle door 300 located in the inner space of the vehicle body 200 can be gradually rotated to the outside of the vehicle body 200 by the movement of the transmission assembly 130. Therefore, the angle at which the vehicle door 300 can be rotated is not easily limited to the vehicle body 200. Even if the door 300 can be rotated at a large angle, the door 300 is less likely to contact the vehicle body 200 to generate friction, thereby facilitating the door 300 to be rotated at a large angle to facilitate the passengers to get on or off the vehicle.

In addition, because the rotatable angle of the vehicle door 300 is not easily limited by the vehicle body 200, the possibility that the vehicle door 300 is rubbed with the vehicle body 200 in the rotating process can be reduced without designing a complex avoidance angle, so that the processing difficulty of the fender can be effectively reduced, the processing efficiency of the vehicle can be improved, and the processing cost can be reduced.

Illustratively, the following landing bits are defined for ease of description and understanding. The transition positions of the first rod 131 and the first transition portion 112 are first transition positions. The transition positions of the second rod 132 and the first transition portion 112 are second transition positions. The transition positions of the first rod 131 and the third rod 133 are third transition positions. The transition position of the third rod 133 and the second transition portion 122 is a fourth transition position. The transition positions of the fourth rod 134 and the second transition part 122 are fifth transition positions. The switching position of the second rod 132 and the third rod 133 is a sixth switching position. The switching positions of the second rod 132 and the fourth rod 134 are seventh switching positions.

The hinge 100 of the embodiment of the present application maintains the position of the body mount 110 unchanged during the switching between the folded state and the unfolded state. The positions of the first and second transition bits may remain unchanged at all times. The first rod 131 and the second rod 132 can rotate around the first transition position and the second transition position, respectively. The third lever 133 and the fourth lever 134 are rotatable about a fourth transition position and a fifth transition position, respectively. The first rod 131, the second rod 132, the third rod 133 and the fourth rod 134 may be rotatably connected to each other through a third through connection position, a sixth through connection position and a seventh through connection position. The positions of the third switching position, the fourth switching position, the fifth switching position, the sixth switching position and the seventh switching position can be translated in a horizontal plane.

The number and relative movement relationships of the levers and the adapter can affect the range of movement of the drive assembly 130, thereby allowing the angle at which the door 300 can be rotated to be adjusted. First link 131, second link 132, third link 133, fourth link 134, door carrier 120, and body carrier 110 of hinge 100 of the present application may be pivotally connected by seven through-connections to increase the maximum angle door carrier 120 can pivot relative to body carrier 110.

Since the hinge 100 of the embodiment of the present application can realize a large rotation angle, the maximum rotation angle can be set according to passengers of different sizes and body shapes. For example, the maximum rotation angle may be 160 degrees. That is, the maximum angle at which the door 300 can be rotated with respect to the body 200 is 160 degrees. At this time, the door 300 may be rotated out of the inner space of the vehicle body 200 and turned to the front end of the vehicle. The door 300 may be located entirely outside the vehicle body 200 so that the passage of passengers to get on or off the vehicle is not easily blocked by the door 300. Even passengers with high stature and strong body can get on or off the vehicle more conveniently.

In some examples, and taking the orientation shown in FIG. 1 as an example, body mount 110 may be located to the left of door mount 120 in the folded state of hinge 100. Body mount 110 and door mount 120 may be spaced apart to provide a space for movement of transmission assembly 130. The hinge 100 may apply a force to the door 300 side in the process of switching the folded state to the unfolded state. Illustratively, the door carrier 120 rotates in a clockwise direction. At this time, the fifth switching position and the seventh switching position on the fourth rod 134 and the fourth rod 134 rotate clockwise, the sixth switching position on the second rod 132 and the second rod 132 also rotate clockwise, so as to drive the third rod 133 and the third switching position and the fourth switching position on the third rod 133 to rotate clockwise, and the first rod 131 also rotates clockwise, so that the position shown in fig. 2 is reached, that is, the hinge 100 is in the unfolded state.

Taking the orientation shown in fig. 2 as an example, the fourth transfer location and the fifth transfer location may be located below the first transfer location and the second transfer location when the hinge 100 is in the unfolded state. The positions of the fourth and fifth transfer positions may change the position of the door prop 120, and thus the angle at which the door 300 may be opened.

In some examples, the rotational connection between the four rods of transmission assembly 130 and body mount 110 and door mount 120, and the rotational connection between the four rods, may be via an adapter shaft. Taking the manner in which the first rod 131 and the body mount 110 are rotatably coupled as an example, the first junction 112 may be provided with a first through hole at the first junction. The first rod 131 may be provided with a second through hole at the first junction. The first through hole is matched with the second through hole. The transfer shaft may penetrate the first and second through holes to connect the first rod 131 and the first transfer part 112.

In some realizable manners, referring to fig. 1 and 2, the first rod member 131 and the second rod member 132 of the embodiment of the present application are respectively arranged at intervals with the transition position of the first transition portion 112, that is, the first transition position and the second transition position may be arranged at intervals. The third rod 133 and the fourth rod 134 are spaced from the transition position of the second transition portion 122, i.e., the fourth transition position and the fifth transition position may be spaced.

In some examples, if the first transition position and the second transition position coincide, the first rod 131 and the second rod 132 both rotate around the first transition position, which easily results in a limitation of the range of movement of the first rod 131 and the second rod 132. Therefore, the first and second switching positions are spaced apart from each other, so that the first and

second rods

131 and 132 can rotate around the first and second switching positions, respectively, and the third and

fourth rods

133 and 134 can be driven to rotate through the remaining switching positions, which is beneficial to increasing the rotatable angle of the hinge 100.

In some examples, with reference to the orientation shown in fig. 1, the fifth transition may be located to the right of the fourth transition with the hinge 100 in the folded state. Referring to the orientation shown in fig. 2, the fifth switching position may be located at the left side of the fourth switching position in the unfolded state of the hinge 100 to change the rotatable angle of the door connecting portion 121, so that the maximum angle at which the hinge 100 can be rotated may be increased.

In some examples, the distance between the first and second transition locations and the distance between the fourth and fifth transition locations are not limited in this application. For example, the distance between the first transit bit and the second transit bit and the distance between the fourth transit bit and the fifth transit bit may be equal.

In some realizable manners, referring to fig. 1 and 2, the first rod 131 intermediate region of the present embodiment is bent toward the vehicle body connection portion 111. The fourth lever 134 is bent at a middle area thereof toward the door link 121.

The first rod 131 is bent toward the vehicle body connecting portion 111 to form a first bent portion 1311. The first bent portion 1311 may form a first escape space in a direction away from the vehicle body connecting portion 111. The fourth bar 134 is bent toward the door connecting portion 121 to form a second bent portion 1341. The second bent portion 1341 may form a second escape space in a direction away from the door connecting portion 121.

In the process of switching the hinge 100 from the folded state to the unfolded state, the first lever 131 and the second lever 132 rotate clockwise with reference to the directions shown in fig. 1 and 2. When the first rod 131 rotates to the position shown in fig. 2, the second transition position may be located in the first avoidance space, so that the possibility that the first rod 131 contacts the transition shaft at the second transition position to affect the rotation range of the first rod 131 can be reduced. Similarly, the fourth transition position may be located in the second avoidance space, so that the possibility that the fourth rod 134 contacts the transition shaft at the fourth transition position to affect the rotation range of the fourth rod 134 may be reduced.

In some realizable manners, referring to fig. 1 and 2, an area of the second rod 132 between the transition point formed by the second rod 132 and the third rod 133 and the transition point formed by the second rod 132 and the first transition portion 112 in the embodiment of the present application is bent toward the vehicle body connecting portion 111, that is, an area of the second rod 132 between the sixth transition point and the second transition point is bent toward the vehicle body connecting portion 111 to form a third bent portion 1321.

The region of the third rod 133 between the transition position formed by the second rod 132 and the third rod 133 and the transition position formed by the third rod 133 and the second transition portion 122 is bent toward the door connecting portion 121, that is, the region of the third rod 133 between the sixth transition position and the fourth transition position is bent toward the door connecting portion 121 to form a fourth bent portion 1331. An area of the third rod 133 near the transition location formed by the first rod 131 and the third rod 133 is bent away from the first transition portion 112, that is, an area of the third rod 133 near the first rod 131 is bent away from the first transition portion 112 to form a fifth bending portion 1332.

Referring to fig. 2, in the unfolded state of the hinge 100, the fourth bent portion 1331 and the fifth bent portion 1332 of the third rod 133 may form a larger third avoiding space in a direction in which the third rod 133 faces the vehicle door 300, and the third bent portion 1321 of the second rod 132 may form a larger fourth avoiding space in a direction in which the second rod 132 faces the vehicle door 300, so that a possibility that a partial region of the vehicle door 300 contacts the transmission assembly 130 during the movement of the transmission assembly 130 to influence the rotation of the vehicle door 300 may be reduced.

In addition, the third bending portion 1321 of the second rod 132 can improve the structural strength of the second rod 132. The fourth bent part 1331 and the fifth bent part 1332 of the third rod 133 may improve the structural strength of the third rod 133, so that the possibility of the second rod 132 and the third rod 133 being broken during the rotation process may be reduced.

In some examples, the length of second bar 132 and third bar 133 in the deployed state of hinge 100 shown in fig. 2 may affect the distance between door carrier 120 and body carrier 110. The second and

third links

132 and 133 may have a length greater than that of the first and

fourth links

131 and 134 so that the door prop 120 may be spaced apart from the body prop 110 during deployment of the hinge 100, thereby reducing the possibility of contact between the door 300 and the body 200 affecting the opening or closing effect of the door 300.

In some realizations, referring to fig. 1 and 2, the transmission assembly 130 of the embodiments of the present application further includes a first limit portion 1322 and a second limit portion 1342. The second rod 132 is provided with a first position-limiting portion 1322. The fourth rod 134 is provided with a second limiting portion 1342. When door carrier 120 is in the open position, first limit portion 1322 is coupled to second limit portion 1342. When the door prop 120 moves from the open position to the closed position, the first limit portion 1322 and the second limit portion 1342 are separated.

The first limit portion 1322 and the second limit portion 1342 of the embodiment of the present application may be disposed on the second rod 132 and the fourth rod 134, respectively, so that it is not necessary to additionally dispose other limit devices to limit the maximum angle that the vehicle door 300 can rotate, thereby being beneficial to reducing the number of used vehicle components, reducing the difficulty of vehicle assembly, and saving the processing and assembly costs.

The first limit portion 1322 and the second limit portion 1342 are in contact only when the door carrier 120 reaches the open position. When the door support 120 leaves the open position, the first limiting portion 1322 and the second limiting portion 1342 are separated, so that the first limiting portion 1322 and the second limiting portion 1342 do not contact with each other in the process of opening or closing the door 300, and therefore friction loss does not occur between the first limiting portion 1322 and the second limiting portion 1342, and the possibility that the first limiting portion 1322 and the second limiting portion 1342 rub against each other to generate abnormal sound or damage to cause limiting failure is reduced.

The first and

second limit portions

1322 and 1342 may be used to define a maximum angle at which the vehicle door 300 may be rotated relative to the vehicle body 200. Referring to the orientation shown in fig. 1 and 2, during deployment of the hinge 100, the door 300 rotates clockwise relative to the body 200. When the first position-limiting portion 1322 is connected to the second position-limiting portion 1342, the second position-limiting portion 1342 can restrict the first position-limiting portion 1322 to rotate clockwise continuously, so that the vehicle door 300 stops rotating. At this time, the positions of the first rod 131, the second rod 132, the third rod 133 and the fourth rod 134 are not changed.

In some examples, referring to fig. 2, in the unfolded state of the hinge 100, at least parts of orthographic projections of the second rod 132 and the third rod 133 along the axial direction of the adapter shaft may coincide.

In some realizable manners, referring to fig. 1 and fig. 2, a first limiting portion 1322 is disposed on the second rod 132 on a side of the transition position formed by the second rod 132 and the fourth rod 134, which faces away from the third rod 133, that is, the first limiting portion 1322 is disposed on a side of the seventh transition position on the second rod 132, which faces away from the third rod 133. A second limiting portion 1342 is disposed on the fourth rod 134 at a side of the transition position formed by the second rod 132 and the fourth rod 134, which is away from the third rod 133, that is, the second limiting portion 1342 is disposed on the fourth rod 134 at a side away from the third rod 133.

In some examples, the first position limiting portion 1322 may be a cylindrical structure. The second position-limiting portion 1342 may be convexly disposed on a side of the fourth rod 134 facing away from the third rod 133. The first position-limiting portion 1322 and the second position-limiting portion 1342 may be rigid structures, so that when the first position-limiting portion 1322 and the second position-limiting portion 1342 contact, the movement of the transmission assembly 130 is stopped. In addition, the first limiting portion 1322 and the second limiting portion 1342 of the rigid structure have higher reliability, so that the possibility that the first limiting portion 1322 and the second limiting portion 1342 are deformed when being triggered to change the rotatable angle of the vehicle door 300 can be reduced.

In some realizable forms, as shown in fig. 1 and 2, the second rod 132 of the present embodiments includes an adaptor end 1323. The transition end 1323 is located on a side of the transition formed by the second rod 132 and the fourth rod 134 facing away from the third rod 133. That is, the transit end 1323 is located at a side of the seventh transit position on the second rod 132 facing away from the third rod 133. Illustratively, the adapting end 1323 is provided with a first limiting portion 1322.

In some examples, the vehicle of the present application may include a drive device. The drive device may be coupled to the transition 1323. Referring to the orientation shown in fig. 1 and 2, the drive mechanism may drive the transition end 1323 to rotate in a clockwise direction to open the door 300 via the transmission assembly 130. The driving device can also drive the transition end 1323 to rotate in the counterclockwise direction to close the vehicle door 300 through the transmission assembly 130.
